Hi John, i just installed multigtfs 0.3.1, started from a fresh PostGIS database, synced the database, and then ran python manage.py migrate multigtfs and got the following error

Running migrations for multigtfs:
 - Migrating forwards to 0015_populate_field_route_geometry.
 > multigtfs:0001_initial
 > multigtfs:0002_auto__chg_field_fare_transfers

FATAL ERROR - The following SQL query failed: ALTER TABLE "shape_point" ALTER COLUMN "point" TYPE geometry(POINT,4326), ALTER COLUMN "point" SET NOT NULL, ALTER COLUMN "point" DROP DEFAULT;

I can duplicate on Postgis but not spatialite. Looks like 0.3.2 is coming soon.
